HEAT-DISTRIBUTER FOR GAS-STOVES, I

Specification of Letters Patent. Patented NO 23 1915 I Applicationfiled. February 14, 1913. Serial'No. 748,269.

' time to heat a column of air immediately above the position which thegas flame would assume, if not thus distributed.

Further purposes of myinvention will appear in the specification andclaims hereto.

I have preferred to illustrate my invention by a form thereof which ispracticable, efiicient and relatively inexpensive and which atthe sametime well illustrates the principles of my invention.

Figure l .is a vertical section through my distributer and a gas stoveburner. Fig. 2 is top plan view of thestructure in Fig. 1. Fig. 3 isbroken perspective of my heat distributer. Fig. 4: is a broken verticalsection of a gas burner and my distributer in reversed position.

In the illustration, the gas burner l is provided with a series of jetsof flame 2 here shown as arranged radially in lines as at 3. In order toprevent the flame from coming in direct contact with the bottom of thepan or utensil, which may be objectionable with utensils having thinbottoms, I place a channeled spacer over each line of jets or of flameand form the upper edge of my attachment as a support for the utensil.

In the preferred position of the attachment shown, I provide a center 4.which may be closed, even if there are no jets at this point in theburner selected, and from which I project radially extending channeledarms 5 having the bottom 6 of each channel close to the jet, causing theflame to spread on each side and come up around the. edges 7 and 8 ofthe channel at the same time that the air within the channel becomesheated by reason of the heating of the bottom and sides.

I inclose the space at the center and the annulus 9, surrounding andconnecting the radial arms, except as these spaces are open to thechannels of the arms, as at lOand 11. The end walls 12 and 13 about theopenings 14 preferably connect with the walls 6 and 7 and the annulus'9is inclosed by a' circular Wall "15 forming a rim. The distributer isintended to rest upon any ribs 16 of the burner.

- While my heat distributer will ordinarily be sold as an article ofmanufacture, separately'from the stoves it is intended to cooperate withthe form of stove with which it is to be used and is to be provided inshapes and sizes such that the channels will correspond to lines of jetsof the burners used,

forming a combination, in each case with the burner for which it isspecially adapted.

The structure may readily be stamped from sheet metal to leave the uppersurfaces of the walls 7, 8, 12, 13 and 15 within a single plane, notonly for the even support of the pan or utensil, but to retain the hotair effectively within communicating spaces. The direct heat from theflame strikes the bottom of the channel in each case and is divided intotwo parts on opposite sides of the channel, giving distributed heatingeffect to each line of jets and giving indirect heating by the heatedair within the channels. The central closed space and outer annulus,both closed except for their communication with the channels, are welland uniformly heated from the channels.

It will be seen that I obtain both direct and indirect heating of thepan along the line of the radial arms and that I obtain indirect heatingof the pan both within and without the area generally heated by thelines of gas flame. My distributer may also be used in reversedposition, as in Fig. 4, to space the pans from the burner and toincrease the eifective thickness of metal between the flame and thecontent of the pan.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In combination, a gas burner providing a gas flame in well-definedlines of flow, a plurality of channels corresponding to the lines of gasflame, interrupted walls forming an inner compartment communicating withthe channels, interrupted outer walls uniting adjoining channel wallsand an outer wall surrounding the interrupted walls and defining betweenit and them an outer compartment communicating with the channels, thetops of the channels and walls lying subthe bottom of the channels.

2. A gas burner having radial gas jets, a plurality of radially disposedchannels adapted to lie in line with and over said gas jets, and annulusconnecting the radial channels, rim sections around'the inside of theannulus between the radial channels and connecting Withthe edges of thechannels,

a rim about the outside of the annulus, a

center connecting the radial channels and rim pcrtions about the centerconnecting the 10 channel edges, the channel sides and the several rimparts being of substantially the same HELEN I. KAUTEFMAN, WM. STEELLJACKSON.
